Litaba tsa Indasteri: Lintlha tsa Bohlokoa bakeng sa Likarolo tsa SMT tse Tšepahalang Haholo Litsamaisong tsa Sejoale-joale tsa Elektroniki

Disebedisweng tsa elektroniki tsa kajeno tse nang le bongata bo phahameng le lebelo le phahameng, disebediswa tsa ho kenya hodima metsi (SMDs) e se e le motheo wa moralo wa potoloho ya sejwalejwale. Ka nqane ho di-capacitor, di-resistor, di-inductor, di-filter tsa EMI, le di-thermistors di bopa tikoloho ya bohlokwa ya dikarolo tse sa sebetseng e netefatsang botsitso, tshebetso e thibelang tshitiso, le ho tshwarella ha nako e telele ditshebedisong tsa indasteri, tsa dikoloi le tsa semiconductor.

Li-resistors tsa chip ke likarolo tse sebelisoang haholo, tse fanang ka moeli o nepahetseng oa hona joale, karohano ea motlakase, le ho fokotsoa ha lets'oao. Li-resistors tsa filimi e tšesaane tse nepahetseng haholo li fana ka mamello e tlase (e ka tlase ho ± 0.1%), coefficient e tlase ea mocheso (TCR), le botsitso bo botle, e leng se etsang hore li be ntle bakeng sa ho lekanya, ho kenya lisebelisoa le lipotoloho tsa puisano. Li-resistors tsa motlakase, ka lehlakoreng le leng, li tšehetsa ho qhala ha matla a mangata 'me li sebelisoa hangata tsamaisong ea matla, taolo ea enjene le litsamaiso tsa ho khanna indasteri.

Li-inductor tsa chip le li-inductor tsa motlakase li bapala karolo ea bohlokoa polokelong ea matla, ho sefa le phetohong ea DC-DC. Ka khanyetso e tlase ea DC (DCR) le motlakase o phahameng oa saturation, li fokotsa tahlehelo ea matla ka katleho le ho ntlafatsa katleho ea phetoho. Li-inductor tsa maqhubu a phahameng li tšehetsa lipotoloho tsa maqhubu a radio (RF) le lebelo le phahameng, li boloka botšepehi ba lets'oao ha li ntse li fokotsa tšitiso ea motlakase.

Likarolo tsa ho thibela EMI, ho kenyeletsoa le li-chip beads, li-common-mode chokes, le li-low-pass filters, li sireletsa lipotoloho tse bonolo lerata la kantle le tšitiso ea ka hare. Likarolo tsena li bohlokoa haholo liphuthelong tsa semiconductor, lisebelisoa tsa elektroniki tsa likoloi le lisebelisoa tse bohlale, moo phetiso e tsitsitseng ea lets'oao e amang ka kotloloho ts'ebetso le polokeho ea sehlahisoa.
Li-thermistors le li-varistor li fana ka tšireletso ea bohlokoa ea mocheso o feteletseng le motlakase o feteletseng. Li-thermistors tse nang le mocheso o fosahetseng (NTC) li hlokomela liphetoho tsa mocheso oa nako ea sebele, li thibela ho chesa haholo li-module tse nang le matla a phahameng. Li-varistor li monya li-voltage tsa maqhubu ka potlako, li sireletsa li-chips le liboto tsa potoloho ho tsoa ho li-spikes tsa motlakase le tšenyo ea motlakase.

Khetho ea likarolo e tlameha ho nahana ka boholo ba sephutheloana, ts'ebetso ea motlakase, mamello ea tikoloho, le maemo a ts'epo joalo ka AEC-Q200 bakeng sa lits'ebetso tsa likoloi. Liphutheloana tse nyane (0402, 0201, 01005) li nolofalletsa bongata bo phahameng ba PCB, ha likarolo tse thata li boloka botsitso tlas'a mocheso o phahameng, mongobo le ho thothomela.

Ha lisebelisoa tsa elektroniki li ntse li tsoela pele ho fetoha ho ea ho miniaturization, maqhubu a phahameng le bohlale, ts'ebetso ea li-resistors tsa chip, li-inductor, li-filters le likarolo tsa tšireletso li tla lula li le bohlokoa moralong oa sistimi. Ho khetha likarolo tsa SMT tsa boleng bo holimo le tse tsitsitseng ke senotlolo sa ho ntlafatsa ts'epo ea sehlahisoa, ho fokotsa sekhahla sa ho hloleha, le ho ntlafatsa tlholisano ka kakaretso.
